Beats Solo 4 review: Upgraded audio, extended battery life and familiar design

When Beats introduced the Solo 3 in 2016, the headline feature was the inclusion of Apple’s W1 audio chip. This delivered seamless pairing with Apple devices, which made life much easier for iPhone, Mac and iPad owners. Besides the noise-canceling Solo Pro in 2019, Beats hadn’t updated the Solo line in nearly eight years, and it’s now bringing its popular on-ear headphones up to today’s standards. Beats announced the Solo 4 today, a $200 set of familiar-looking cans with significant updates to audio quality and battery life. But as it has done on other devices, the company has chosen its own audio platform over Apple’s AirPod chip.
